Drop pointless local variable in snprintf callbacks
A common idiom among snprintf callbacks was to copy the unsigned
parameter 'size' (or 'len') into a signed variable for further use.
Though since snprintf() itself casts it to unsigned and
SNPRINTF_BUFFER_SIZE() does not allow it to become negative, this is not
needed. Drop the local variable and rename the parameter accordingly.
